FIRE SUPPRESSION SYSTEM DIAGNOSTICS MESSAGES
OPEN THERMISTOR PROBE – This message indicates that the fire suppression system thermistor probe
either
is not connected or is damaged. If this condition is detected, the microprocessor controller (computer) will
immediately enter S.A.F.E. SYSTEM DISABLED Mode.
SHORTED THERMISTOR PROBE – This message indicates that the fire suppression system thermistor
probe is damaged or the wiring is shorted. If this condition is detected, the microprocessor controller (computer)
will immediately enter S.A.F.E. SYSTEM DISABLED Mode.
DISCONNECTED WATER VALVE – This message indicates that the water valve is open or that it is not
connected to the microprocessor controller (computer). If this condition is detected, the microprocessor controller
(computer) will continue to monitor the condition for a period of 5 minutes before entering S.A.F.E. SYSTEM
DISABLED Mode. Once the condition is corrected, the microprocessor controller (computer) will continue to
monitor the condition for 1 minute before exiting S.A.F.E. SYSTEM DISABLED Mode.
SHORTED WATER VALVE – This message indicates that the water valve is shorted or that the wiring to the
valve is shorted. If this condition is detected, the microprocessor controller (computer) will continue to monitor
the condition for a period of 5 minutes before entering S.A.F.E. SYSTEM DISABLED Mode. Once the
condition is corrected, the microprocessor controller (computer) will continue to monitor the condition for 1
minute before exiting S.A.F.E. SYSTEM DISABLED Mode.
WATER NOT CONNECTED – This indicates that there is no water pressure at the water valve. This will
occur if water is not connected to the dryer, or if there is low water pressure in the water line coming to the
dryer. This could also signify a defective pressure switch or defective wiring to the pressure switch. If this
condition is detected, the microprocessor controller (computer) will continue to monitor the condition for a period
of 5 minutes before entering S.A.F.E. SYSTEM DISABLED Mode. Once the condition is corrected, the
microprocessor controller (computer) will continue to monitor the condition for 1 minute before exiting S.A.F.E.
SYSTEM DISABLED Mode.
STARTING A CYCLE WHEN MICROPROCESSOR CONTROLLER
(COMPUTER) IS IN “S.A.F.E. SYSTEM IS DISABLED” MODE
When the fire suppression system is disabled, the user can still start a cycle. However, when a cycle is started,
the non-coin microprocessor controller (computer) will display the following message, “S.A.F.E. SYSTEM IS
DISABLED. PRESS ‘START’ TO CONTINUE”. This message will be displayed every time a cycle is
started, until the disabling condition has been corrected.
